Star Wars Episode VII will be set 30 years after Episode VI: Return of the Jedi• It will indeed feature the Skywalker/Solo children coming to the peak of their powers
• The Jedi Order has been rebuilt with Luke Skywalker as Grand Master
• A disciple of Emperor Palpatine aims to rebuild the Sith Armies of the Old Republic and destroy the Jedi where the Skywalker children will be thrust into battle and face their inner demons of their Skywalker lineage.
Nothing there surprises me, as it was obvious that's where the story is going. The key will be making the new villain(s) fresh and original rather than a tired rehash of previous ones.
